I have WCS 3.2.64, WLC4404 220.127.116.11, 1242 LWAPP APs, and a 2700 Location Appliance. I am running into an issue where the wireless clients (MS managed, mostly Cisco and Intel cards) stop recieving DHCP addresses. There are no errors being generated in any of the logs to indicate why the DHCP clients are not being issued IP addresses. Also, we are using IAS on Win2k3 as authentication server. The clients are logged as good logins. This all works fine for anywhere between 1 day and 1 week, then it all just stops passing DHCP addresses out. The same DHCP server is handing out addresses to wired clients as well, so the DHCP server appears ok. Many times I am only told about the problems much later and have a hard time nailing down the exact time it starts, so I am log-boy for a day reading the last couple of days worth trying to glean some kind of failure. Any ideas on how I can capture this when it happens and try to nail down what is causing it? Thanks in advance!
